Driving and operating
Brakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when you depress the
brake pedal firmly. You need to use
considerably more force for this. The
braking distance is extended. Seek
the assistance of a workshop before
continuing your journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has
been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear
this in mind when being towed.

If the brake pads wear to a
predetermined point, the braking
system will require inspection. Seek
the assistance of a workshop.

Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.
ABS starts to regulate brake pressure
as soon as a wheel shows a tendency
to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that
the pedal is pulsating. Do not reduce
the pressure on the pedal.

Fault
If control indicators
u
and
A
illuminate with the messages CHECK
ABS and CHECK ESP in the Driver
Information Centre, there is a fault in
the ABS. The brake system remains
operational but without ABS
regulation.

Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS
are no longer available. During
hard braking, the vehicle can no
longer be steered and may
swerve.
If control indicators
u
,
A
,
R
and
C
illuminate, the ABS and ESP are
deactivated and the message
BRAKING FAULT is shown in the
Driver Information Centre. Seek the
assistance of a workshop.
Have the cause of the fault remedied
by a workshop.
